摘要： A fault diagnosis system for a rotor winding of rotary electric machines is disclosed, in which the rotor winding of rotary field type is excited in DC fashion by an excitation circuit, on which an AC voltage is superposed, the impedance of the rotor winding is calculated from the current and voltage of the AC portion flowing in the rotor winding, and the resulting impedance is compared with a reference impedance thereby to decide a fault, if any, of the rotor winding, thus making possible accurate diagnosis of a rotary electric machine even while it is running.

摘要： A method of adjusting a thermal balance of a rotor. When obtaining a difference in shaft-vibration component of the rotor between an actual load condition and a no load condition, on the basis of detection results at a simulated load, a difference in shaft-vibration component of the rotating rotor between a no-load condition and a condition in which the rotor is heated from the outside and a difference in shaft-vibration component of the rotating rotor between a no-load condition and a condition in which the rotor is heated from the inside are detected at the simulated load. The detected differences in shaft-vibration component are converted respectively to differences in shaft-vibration component under a temperature condition at the actual load. Both the converted differences in shaft-vibration component are added to each other in a vector manner to obtain a difference in rotor shaft-vibration component at the actual load. Coolant flow rate at each section within the rotor is adjusted to eliminate the difference in rotor shaft-vibration component, thereby adjusting the thermal balance of the rotor.

摘要： In a stator core support structure in a conventional rotating electric machine, it has been difficult to set the circumferential and radial stiffnesses with which elastic bars support a stator core, to appropriate values in view of a relationship between transmission of torque and vibration prevention. In order to solve the above problem, sectional shape of elastic support bars is formed as rectangular, elliptic, rhombic or the like, and accordingly, the ratio between circumferential and radial stiffness of the elastic support bars can be changed.
